Zach York updated HBASE-18520:
    Release Note: 
This JIRA adds a JMX value to track when the Master has finished initializing.
The jmx config is 'masterFinishedInitializationTime' and details the time in 
millis that the Master is fully usable and ready to serve requests.

> Add jmx value to determine true Master Start time
